What is the hybrid 'deltacron' variant of the coronavirus?

STAT outlines some of the factors that are influencing case rates and parses some of what could happen next.

Germany, a nation of 83 million people, saw more than 250,000 new cases and 249 deaths Friday, when Health Minister Karl Lauterbach called the nation’s situation “critical.” The country is allowing most coronavirus restrictions to end Sunday, despite the increase. Britain had a seven-day average of 65,894 cases and 79 deaths as of Sunday, according to the Johns Hopkins University Coronavirus Research Center. The Netherlands, home to fewer than 18 million people, was averaging more than 60,000 cases the same day.

In all, about a dozen nations are seeing spikes in coronavirus infections caused by BA.2, a cousin of the BA.1 form of the virus that tore through the United States over the past three months.

In the past two years, a widespread outbreak like the one now being seen in Europe has been followed by a similar surge in the United States some weeks later. Many, but not all, experts interviewed for this story predicted that is likely to happen. China and Hong Kong, on the other hand, are experiencing rapid and severe outbreaks, but the strict “zero covid” policies they have enforced make them less similar to the United States than Western Europe.
